At my job and in between the stuff there is a mix in between LPNs and MAs and both perform the same kind of dutties. A MA is actually the "nurse mananger". Can a MA supervise LPNs? I was reading about what a MA is and it looks like they can do as much as the LPNs, am I wrong? Do MAs need to be license to work? I work in a plastic surgery clinic in Florida. I am really confuse about the difference in between this two. Which one has the grater tittle?.
